Laser Desorption/Ionization-Time of Flight (LDI-TOF) and Matrix-Assisted Laser Desorption/Ionization - Time of Flight (MALDI – TOF) mass spectrometry of an Algerian asphaltene

Both LDI-TOF and MALDI-TOF Mass spectroscopy experiments of an Algerian asphaltene derived from a deposit were performed. LDI mass experiments were conducted for both linear and reflectron modes under laser wavelength/attenuation variation. The different LDI-Mass spectra show that mass distribution...
